Arduino – an introduction

Arduino is an opensource platform which is an easy to use hardware-based development, This development boards are commonly used Atmel based microcontroller which is programmed by using Arduino IDE(Integrated Development Environment). This freeware can be downloaded from the Arduino official site or use can program in a web-based platform named as Arduino create

Arduino programming

Once you purchase Arduino UNO (buy now ) you can connect with the computer after installing Arduino ide, Then you need to choose the development board and port from the tools option

Adruino was written in C++ also with some other functions and specific methods which are called as a sketch in Arduino IDE and then it process and compiles to machine language

Serial monitoring

For open serial monitoring option, we can see a magnifying glass icon in the right top of the Arduino IDE. This tool is mainly used for interacting the Arduino development board with the computer. Which means this tool help to debug and monitoring of the real-time program similarly like serial monitor Arduino also have a serial plotter which helps to plot the graph of a realtime running Arduino application
